EDMOND I-IOYE, OF CENTRALIA, ILLINOIS, ASSIGNOR OF ONE-HALF TO JOSEPH V. LANGENFELD, OF CENTRALIA, ILLINOIS.

FRICTIONAL DRIVING CONNECTION.

Specification of Letters Patent.

Patented Oct. 6, 19141.

To all whom it may concern:

Be it known that I, EDMOND Horn, a citizen of the United States, residing at Centralia, in the county of Marion and State of Illinois, have invented certain new and useful Improvements in Frictional Driving Connections; and I do declare the following to be a full, clear, and exact descri'ption of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention is a frictional driving connection for reels and the like and particularly adapted for the reels of gathering motors used on electrically operated coal cars and means whereby the electric current conducting cable is wound up and unwound when the cars move in one direction or the other.

One object of the invention is to provide a friction drive of this character which will slip around without turning the cable winding reel when the wheels of the car or locomotive to which the reel is geared slip around on the tracks and fail to propel the car, thus obviating all danger of breaking the electric cable, which would occur should the reel be driven while the car was not moving.

Another object is to provide a friction device of this character having an improved means for adjusting the friction mechanism thereof and maintaining the same at the proper tension.

With these and other objects in view, the invention consists of certain novel features of construction and the combination and arrangement of parts as will be more fully described and claimed.

In the accompanying drawings; Figure 1 is a longitudinal section of a cable gathering or winding reel embodying my invention; Fig. 2 is a transverse section of the same taken on the line 2-2 of Fig. 1; Fig. 3 is a similar view taken on the line 3-3 of Fig. 1; Fig. el is a detail perspective view of the friction end of the cable Winding drum of the reel; Fig. 5 is av similar View of one of the friction disks; Fig. 6 is a similar view of the driving disk; Fig. 7 is a perspective view of the other friction disk which corresponds with the friction disk shown in Fig. 5; Fig. 8 is a detail perspective view of the drive shaft of the reel; Fig. 9 is a similar view of one of the keys for locking the friction disks to the friction ring; Fig. 10 is a detail perspective view of one of the adjusting screws.

Referring more particularly to the drawings, 1 denotes the drive shaft of my improved reel, said shaft being re-volubly mounted in a suitable supporting frame or casing 2. Loosely mounted on the shaft 1 is the cable winding drum or cylinder 3 of the reel, said drum having on one end a removable flanged head 4 and on its opposite end a fixed flanged head 5. The heads 4 and 5 have formed thereon centrally. disposed bearing sleeves 6 which are provided with suitable bushings 7 which engage the shaft 1 as shown. The shaft 1 is provided at one end of the drum 8 with a sprocket gear 8 or other suitable driving mechanism whereby said shaft is operatively connected with and driven by one of the driving and supporting shafts or axles of the car or locomotive to which the device is applied. The shaft 1 is operatively connected with the drum or cylinder 3 of the reel by my improved friction driving mechanism which will now be described.

It might be here statedthat the previously described parts of the device as well as such other parts that are necessary for connecting the drive shaft 1 with the driving and supporting shaft of the car or locomotive may be of the usual construction employed in connection with devices of this character and do not form a part of the present invention. A further description or illustration of these common and well known parts is not thought to be necessary.

My improved friction driving mechanism for the cable winding drum or cylinder 3 of the reel comprises a friction ring 9 loosely mounted on the drive shaft 1 and which is fitted in and rigidly fixed to one end of the drum or cylinder in any suitable manner. The friction ring 9 is cup-shaped, its periphery disposed in the end of the drum adjacent to the removable flanged head 4 of the latter and its inner wall 9 loose around the shaft. At diametrically opposite points in the inner surface of the ring are formed longitudinal grooves or key-ways 10 with which are engaged keys 11. The friction ring 9 is held from moving inward within the drum 3 by means of a long sleeve 90 extending from its inner wall 9 to the bushing 7 of the fixed head 5. Disposed within the friction ring 9 and having a loose engagement with the drive shaft 1 are outer and inner friction disks 12 and 13 in whose edges at diametrically opposite points are formed rectangular notches 14; adapted to receive the keys 11 whereby said disks are keyed or locked to the friction ring to turn therewith, said disks however, having a longitudinal sliding engagement with the keys 11 and inner surface of the friction ring. The drive shaft 1 for a short distance between the inner and outer friction disks 12 and 13 is squared as at 1 and on said squared portion is fixed an intermediate friction or driving disk 15 which is of less diameter than the disks 12 and 13 and is adapted to turn in the friction ring between the oppositely-disposed keys 11 vhich lock the friction disks 12 and 13 to the ring.

()n the outer side of the disk 12 are a series of longitudinally extending springsupporting pins 16 on each of which is arranged a coiled spring 17. he outer ends of the springs 17 are engaged with the re duced inner ends of spring adjusting screws 18 which have a threaded engagement with the removable head 4 onthe adjacent end of the cable winding drum or cylinder 3. T he outer ends of the adjusting ws 18 may he provided with heads to receive a wrench or as herein shown said adjusting screws may be provided with slots to receive a screw driver wherehy the adjusting screws may he readily adji'isted for regulatig the pressure or tension of the rings 1?. By arranging the friction disks and the springs 17 as herein shown and described it will be seen that the pressure of said sprin s will be exerted to force the disk into t1 'ht frictional en agement with the driving disk 15, the lat into frictional eugageu'ient with the inner disk 13, and this div into frictional engagement with the inner wall. 9 of the cup-shaped friction ring 9, whereby the power or movement of the drive shaft 1 is imparted to the friction ring and through the latter to the drum or oylind 3 of the reel whereby the latter is revolved in the proper direction for winding up or unwinding therefrom the electric current conducting cable of the motor as the car or locomotive driven thereby is propelled in one direction or the other. By providing the adjusting screws 18 for the springs 1'? it will also be seen that the fric tional engagement of the disks may be regulated according to the load or power re quired of the driving mechanism.

It has been ascertained by practical experiments that my improved friction drive the car or locomotive, thus stopping the movement of the reel and obviating any danger of the electric current conducting cable being broken by the winding move 7 ment of the reel when the car or locomotive is not moving.

The head 4C is rendered removable by any suitable means, such as fastening screws l" passing through it and into the friction ring 9, and when this head is removed the set adjusting screws 18 come off with it and the springs 17 and all the disks are exposed, and may be repaired or cleaned as necessary.

From the foregoing description taken in connection with the accompanying drawings, the construction and arrangement of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention as shown.

Having thus described my invention, what I claim is:

In. a frictional driving connection, the combination with a shaft having a squared portion, a driving disk having a squared hole through it mounted on said portion, means for rotating the shaft, and a drum having a fixed head at one end, and a removable head closing its other end; of a cup shaped friction ring whose inner wall surrounds said shaft at a slight distance from the squared portion thereof and whose periphery is fixed within said drum, internal keys carried by said ring and disposed parallel with the shaft, fastening screws passing through said remo 'able head and detachably engaging the periphery of said ring, disks loose on the shaft at opposite sides of said driving disk and having notched edges slidably engaging said keys, adjusting screws passing through the removable head of said drum, and expansion springs between the inner ends of said adjusting screws and the outermost of the last mentioned disks, for the purpose set forth.

ln testimony whereof I have hereunto m my hand in presence of two subscribing witnesses.

EDMOND HOYE,
